Over the years, I had money then, I have had three implants in the UK from a highly qualified dentist who specialises in implants. They weren't cheap but I have had no problems and am very happy with them. One involved a bone transplant which increased the overall timescale, and cost
there was the dentist and three nurses in the operating room, not his normal dentistry room. I never felt a thing and I fell asleep during the op.
I first had a head CT scan at a local hospital, or it may have been MRI, so he could check the amount of bone available as two of the teeth had been missing for some time, it was a bridge involving three molars .
One day implants were never mentioned, but technology has improved over the years. I think I had at least four separate appointments for each implant.
He inspected a patient with a foreign implant for a TV program which was edited to say it looked OK. He told me it was only just OK, not really good. But there are lots of foreign specialists and I expect that, just as here, some will be really good and some not so good. The problem is finding the really good ones amongst those who have just jumped on the bandwagon.
The cleaning routine for me just involves flossing and brushing twice a day and regular hygienist appointments.
I did meet someone who had got a damaged implant, in a fight?, but he was suffering with it as it needed a specialist operation to remove it and he could not get it done on the NHS and did not have the money to pay privately.
